The German Renewable Act has successfully increased
                              renewable energy capacity from 6% of total generation
                              capacity in 2000 to 16% in 2009. However, in order
                              to compensate for higher demand, lower wholesale
                              prices and last year's levy deficit, German consumers
                              will have to foot a bill of E13.5 billion in 2011.
                              This should be a warning to other countries of
                              the immediate costs of such policies. 
                              
                              Germany's feed-in tariff has been highly successful
                              in terms of increasing the country's renewable
                              energy capacity; solar photovoltaic (PV) cumulative
                              capacity alone grew from 4GW at the end of 2007
                              to about 9GW by the end of 2009. Industry sources
                              suggest that this figure could even double in 2010,
                              a far greater increase than anticipated by the
                              government. Currently, investors are enjoying generous
                              rates for electricity generated from renewable
                              sources; however, as the installed PV capacity
                              has far exceeded the government's expectations,
                              these rates are set to decrease accordingly. 
                            It seems that the government's policy has become
                              a victim of its own success, as solar manufacturers
                              kept quiet about production efficiency savings
                              and were able to successfully hype up sales in
                              the run-up to the proposed cuts to the feed-in
                              tariff. Rapid growth in PV installations, lower
                              wholesale prices (which increase the difference
                              between prices paid and the set feed-in tariffs)
                              and the need to compensate for 2009's levy deficit
                              mean that for 2011 the government needs to find
                              E13.5 billion rather than the E8 billion required
                              in 2010. 
                            The majority of this will be paid for by German
                              consumers, who will see a 70% increase in the renewable
                              energy levy charged to their electricity bills,
                              from 2.05 euro cents per kWh to 3.53 euro cents.
                              For a three-person household using 3,500kWh per
                              month, this will equate to an increase of E6-10
                              on a monthly bill, which is roughly a 10% increase
                              overall. More than half of this increase in the
                              renewable energy levy will be invested in the solar
                              energy sector, despite the fact that it produces
                              less than 20% of the subsidized electricity. 
                            Meanwhile, other countries such as Spain and the
                              UK have cut or adjusted their feed-in tariffs for
                              budgetary reasons. These examples show that installing
                              greater renewable energy capacity comes at a price
                              which initially remains hidden from consumers.
                              Policy makers must ensure that they strike the
                              right balance between encouraging homeowners and
                              local communities to invest in renewables by initially
                              offering appropriate financial returns, while keeping
                              costs to the government and consumers to a minimum.
                              Germany appears to be on track, with plans to generate
                              80% of its electricity from renewable fuels by
                              2050. However, the country's consumers will be
                              paying the price for this success.
